Answer:
y=0.8x
Step-by-step explanation:
take two points from the graph
(5,4) and (0,0)
then do y2-y1/x2-x1
4-0/5-0
4/5=.8
Answer:
Chukwu's share is of $57.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
Chukwu's share is x.
Abdul's share is y.
Kunle's share is z.
Chukwu, Abdul and kunle are to share $142
This means that 
Abdul gets $11.00 less than Chukwu
This means that:

$7.00 more than Kunle.
This means that:

So



How much is Chukwu's share?
We want to find x, so:






Chukwu's share is of $57.
60/100 is 3/5 so Anna colored 60% of the paper blue
Answer:B
Step-by-step explanation:
Using what is known as the "Triangle Inequality Theorem" a+b can not be less than c or else it is not a triangle. (A and B are the smallest sides of the triangle).
A) 6cm + 15cm = 21cm which is less than 23cm: Not a triangle
B) 5cm + 9cm = 14cm which is greater than 13cm: This makes a triangle and therefore the answer is B
C) 5cm + 8cm = 13cm which is less than 13cm: Not a triangle
Answer:
23.05 x 10.85
Step-by-step explanation:
Area of Rectangular Fence = L * W = 250
L * W = 250
W =
................................... (i)
Perimeter = 2L + 2W
Three sides cost 4 dollars per foot = 4(2L) + 4W
(The two lengths must be constructed with the 4 dollars materials)
Fourth side costs 13 dollars per foot = 13W
Cost = 4(2L) + 4W + 13W
C = 8L + 17W ...................................... (ii)
Substitute (i) into (ii)
C = 8L + 17 (
)
C = 8L +
Plotting this equation with L on the x-axis and cost on the y-axis
minimum cost will be when L ≈ 23.05 ft
W =
≈ 10.85 ft
minimum cost = 8(23.05) + 
minimum cost = 184.4 + 184.382
minimum cost ≈ 368.78 dollars
